#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) received a report at the weekend of a large baleen whale struggling in the shallows at Cross Beach in north-west Co Mayo.

The 12-metre marine mammal, thought to be a sei whale or fin whale, was ushered back into deeper waters by a group surfing in the area on Sunday 27 November.

But locals are urged to keep a lookout over the next few days as the whale, believed to be injured or in poor health, is likely to strand again.

#MarineWildlife - Common dolphins stranded in a Kerry river last weekend were saved by the quick actions of local people, as The Kerryman reports.

Trapped by the fast receding tide at the mouth of the Cloghane Estuary on the Dingle Peninsula last Saturday (20 June), the group of dolphins were fortunate they didn't have to wait long for the community to spring into action.

Following a report from local woman Shelia Mulcahy, Louise Overy of Dingle Oceanworld and her sister Tabitha co-ordinated efforts that involved area fishermen and landlubbers alike, keeping the dolphins wet till enough people arrived to help move the protected marine wildlife back into deeper waters.

#MarineWildlife - Locals have been astounded by a mass stranding of up to 200 pilot whales in New Zealand.

According to the Irish Independent, volunteers were yesterday (13 February) fighting to save the whales that were still alive after beaching along a 7km stretch of sand at the north end of New Zealand's South Island.

The death toll was last put at around 25, and while some other were reportedly refloated, they were said to be "swimming in a confused fashion" as the Guardian reports.

Farewell Spit, where the stranding has occurred, is said to be a 'whale trap' for its numerous cases of cetacean strandings - bringing to mind the recent "unusually large number" of whale beachings in Scottish and Irish waters.

#MarineWildlife - A juvenile dolphin was saved after stranding in the shallows at Maree on Galway Bay thanks to the swift actions of a local farmer.

As the Galway Advertiser reports, Martin Costello waded out into the inlet at Ballinacourty - a notorious spot for marine wildlife strandings - to pick up the young cetacean and carry it out to deeper water, from where it was able to swim out to safety.

Such human intervention was invaluable in the rescue of an ailing seal pup that was found alone on a beach in Connemara at the weekend.

According to the Irish Mirror, the infant seal was taken to Seal Rescue Ireland in Athlone, where staff have named him Sea Noodle and are nursing him back to health, though a serious chest infection means he's not out of the woods yet.

#MarineWildlife - Skerries RNLI joined a number of groups in assisting a beached whale back out to sea at Gormanston in Co Meath earlier today (Thursday 20 June).

The volunteer lifeboat crew launched their inshore lifeboat shortly after 10am following reports from the Irish Whale and Dolphin Group (IWDG) that a 25ft pilot whale had beached in the area.

The lifeboat helmed by Joe May, and with crew members Emma Wilson, AJ Hughes and Laura Boylan onboard, made its way to the scene where May got into the sea and helped manoeuvre the whale back into deeper water.



Skerries RNLI then shadowed the whale guiding it out to sea, preventing it from turning back to shore by positioning the boat in its way. The lifeboat did this for about 25 minutes until the mammal was well clear of the shore.

Other agencies on scene included Skerries coastguard, the Defence Forces based at Gormanston, the IWDG, Boyne Fishermen’s Rescue and Irish Coast Guard helicopter Rescue 116.

Meanwhile, RTÉ News reports that a second whale was found dead on the beach near Mornington, north of Bettystown.

Despite initial fears that the whale was the same one rescued in the morning, it was later determined to be a different creature.

#MarineWildlife - Another beaked whale stranding has been recorded on the Irish coast just weeks after two of such creatures were found in Donegal.

A ranger with the National Parks and Wildlife Service (NPWS) made the discovery at Aillebrack in Co Galway on the evening of 27 May.

The 5m carcass of a female - like the female and juvenile found in the northwest - is thought to be either a True's or Sowerby's beaked whale.

Mick O'Connell, strandings officer with the Irish Whale and Dolphin Group (IWDG), says the latest stranding "raises new questions", with suspicion that its death may be linked to the face of the Donegal pair earlier this month.

As previously reported on Afloat.ie, beaked whales are a rare occurrence in Irish waters, with the last record before this month' stranding made in 2009.

#MarineWildlife - Two dolphins saved from stranding on a beach in Donegal leapt from the water "as if to say thank you" after their rescue by a local fish farmer.

The Belfast Telegraph reports that salmon farmer Shea Coyle and his father Michael acted quickly after noticing what at first looked like two upturned surfboards on Downings beach near Fanad.

But what looked from afar like surfboard fins turned out to be the fins of two dolphins that had become trapped in the sand.

Shea described how the dolphins were "trying desperately to wriggle free" before he leant a hand to heave them back into the water.

"After about 10 minutes I got one dolphin safely out into deeper water and he stayed there whilst I got to work on the other."

Once the second dolphin was free, the pair "just took off" - and were later seen by the Coyles from a nearby peer, giving what might just have been a show of thanks.

The happy story in Donegal occurred not long after a series of dolphin and whale strandings in the northwest described as "unusual" by the Irish Whale and Dolphin Group (IWDG).

#MarineWildlife - Seven dolphins and two beaked whales have stranded on beaches in the northwest in events described as "unusual" by the Irish Whale and Dolphin Group (IWDG).

On the Mullet Peninsula, a group of seven common dolphins - comprising five adults and two juveniles - live stranded at Tarmon Beach on Sunday 12 May.

Though initial attempts to refloat them were successful, one of the juveniles was later found dead and the other was euthanised due to poor health.

Meanwhile in Donegal, the fresh carcass of a female True's or Sowerby's beaked whale was found on Sunday evening on Five Fingers Stand at Inishowen - some days after a reported live stranding of a Sowerby's beaked whale on the Welsh coast.

The Inishowen stranding was followed yesterday 14 May by the discovery of a dead beaked whale calf at Trawbreaga Bay, in what is believed to be a connected stranding.

Samples of the adult female were taken in order to confirm the species, either of which would mark a rare cetacean record for Ireland - the first since 2009.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has described as "very unusual" a mass stranding of common dolphins on Achill Island last week - which was followed this week by the remains of cetaceans washed up in Kerry.

At least eight common dolphins were found dead on Keel Beach, Keem Beach and Dookinella on the Co Mayo island at the end of January.

And The Irish Times reports that two pilot whales and an "otherwise healthy" dolphin were found washed up at Cuas Croom near Cahirciveen in the last few days.

Commenting on the former incident, IWDG stranding officer Mick O'Connell said: "While there are occasionally live strandings involving groups of dolphins, it is very unusual in this country to see this number of dead dolphins washed ashore over a 10km area."

Strandings of deceased dolphins have also been reported in Donegal, and the IWDG's Simon Berrow suggests that the recent severe weather experienced around Ireland's coast may be a factor.

#MARINE WILDLIFE - Marine wildlife experts are investigaing the causes of a mass stranding of pilot whales at Fife in eastern Scotland at the weekend.

The Press Association reports that 16 whales from a 26-strong group died when they stranded on a beach near St Andrews on the morning of Sunday 2 September. Three of those that died were calves.

More than 50 volunteers assisted members of the RNLI and vets from British Divers Marine Life Rescue (BDMLR) in refloating the other 10 whales at high tide yesterday afternoon, in what BDMLR co-ordinator Ali Jack described as "a fantastic effort".

Rescuers used specialist pontoons brought in from across Scotland as well as Newcastle and Cumbria in northern England.

According to The Guardian, some 24 whales from the same pod were spotted in the shallows further along the coast at Cellardyke and are under close observation.

A Forth coastguard spokesman said that vets would return to the beach this morning to carry out post-mortems on the whale carcasses to find any indication of what might have caused them to come so close to the shore.

The spokesman told The Guardian: "It is a very rare occurrence in Scotland and very sad. The usual scenario would be that the whale that is leading the group has become ill, or has lost its way, and gets beached and the rest will follow on, although we do not know for sure if that is what happened."

The incident brings back memories of last year's mass stranding of 44 pilot whales in the Scottish Highlands, as previously reported on Afloat.ie.

Twenty-five whales from that pod died at the Kyle of Durness, in a tragedy that mirrored the deaths of 33 whales in a similar mass beaching in Donegal in late 2010.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
